Electrical contactor for terminal pin

Abstract

An electrical contactor is provided which has particular although not exclusive utility in forming an electrical connection with a tungsten terminal pin such as is used in vacuum or gas-filled envelope enclosed high voltage relays; the contactor is in the form of a coil of resilient electrically-conductive material which grips the terminal pin in tight engagement therewith, and it serves as a solder tab for an electric wire to be connected to the terminal pin.

What is claimed is: 
     
       1. An electrical contact assembly comprising: a rigid electric terminal pin; an electrical connector to serve as a soldered tab for an electric wire to be connected to said terminal pin, said connector being formed of a resilient electrically-conductive material to which solder may be rigidly bonded and having a coiled portion adapted to fit over the electrical terminal pin in close fitting coaxial relationship therewith, said coiled portion including a first section wound in one direction and a second section coaxial with the first section and wound in the opposite direction, each of the first and second sections grippingly engaging said rigid terminal pin, and said connector having an exposed central portion shaped to permit an electric wire to be soldered to the connector. 
     
     
       2. The electrical connector defined in claim 1, in which the connector is formed of resilient wire. 
     
     
       3. The electrical connector defined in claim 1, in which the electrical connector has a tab-like portion having one end configured to form said coiled portion. 
     
     
       4. The electrical connector defined in claim 1, in which the electrical connector is formed of beryllium copper. 
     
     
       5. The electrical connector defined in claim 1, in which said connector is formed of phosphor bronze.
